propylene glycol Application:
1.Propylene glycol solution performance is good, less toxicity and irritation, widely used for injection
(such as intramuscular injection, intravenous injection) and non pharmaceutical preparations for injection
(e.g., oral solution, eye ophthalmic preparation, ear preparations, tooth preparations, rectal vaginal preparations,
transdermal preparations, etc.) of the solvent, extraction solvent and preservatives, is better than glycerin solvent.
2.Propylene glycol is similar to ethanol as a bacteriostatic agent, and its inhibitory effect on mold is similar to glycerol,
slightly lower than ethanol.Propylene glycol is commonly used as a plasticizer for water-borne film coating materials.
The same amount of mixture with water can delay the hydrolysis of some drugs and increase the stability of
Warehouse ventilation and low temperature drying.
